This vehicle has theft-deterrent
features; however, they do not make
it impossible to steal.
Anti-theft Alarm System
If your vehicle has the Remote
Keyless Entry (RKE) system, the
vehicle has a content theft-deterrent
alarm system.
To activate the content
theft-deterrent system:
1. Close all the doors.
2. Lock the doors with the RKE transmitter. The security light,
located on the instrument panel
cluster, will flash. If the LOCK button on the RKE
transmitter is pressed, but a door is
open, the horn will chirp six times.
Press the LOCK button again, within
three seconds, and the doors will
lock. Close the open door and the
system will be activated.
If a locked door is not opened using
the RKE transmitter, or by OnStar
®,
the pre-alarm will go off. If the
engine is not started or UNLOCK
not pressed within 10 seconds, the
front turn signal lamps will flash for
two minutes, and the horn will sound
for two minutes, then will turn off to
save the battery power.
Remember, the theft-deterrent
system will not activate if you lock
the doors with a key, the manual
door lock, or power door lock
switch. The system can only be
activated using the RKE transmitter,
or by OnStar
®. See the OnStar
Owner's Guide for additional
information. You should also
remember that you can start your
vehicle with the correct ignition key
if the alarm has been set off.

2-10 Keys, Doors, and Windows
Here is how to avoid setting off the
alarm by accident:
.If you do not want to activate the
theft-deterrent system, the
vehicle should be locked with
the door key after the doors are
closed.
.Always unlock a door with the
RKE transmitter. Unlocking a
door any other way will set off
the alarm.
If you set off the alarm by accident,
you can turn off the alarm by
pressing UNLOCK on the RKE
transmitter. The alarm will not stop
if you try to unlock a door any
other way.
Testing the Alarm
To test the alarm:
1. From inside the vehicle, activate the system by locking the doors
with the RKE transmitter. 2. Unlock the door with the manual
door lock and open the door.
This should set off the alarm.
3. To turn the alarm off, press the UNLOCK button on the RKE
transmitter or start the engine.
If the alarm does not sound when it
should but the lights flash, check to
see if the horn works. The horn fuse
may be blown. To replace the fuse,
see Fuses and Circuit Breakers on
page 10‑39.
If the alarm does not sound or the
front turn signal lamps do not flash,
see your dealer for service.

This vehicle has a passive
theft-deterrent system.
The system is automatically armed
when the key is removed from the
ignition.
The system is automatically
disarmed when the key is turned
to ON/RUN.
You do not have to manually arm
or disarm the system.
The security light comes on if
there is a problem with arming or
disarming the theft-deterrent
system.
The key uses a transponder that
matches an immobilizer control unit

damaged, the vehicle may not start.
When trying to start the vehicle,
if the engine does not start and
the security light comes on, there

may be a problem with the
theft-deterrent system. Turn the
ignition off and try again.
If the engine still does not start, and
the key appears to be undamaged,
try another ignition key. Check
the fuse. SeeFuses and Circuit
Breakers on page 10‑39. If the
engine still does not start with the
other key, the vehicle needs service.
If the vehicle does start, the first key
may be faulty. See your dealer who
can service the theft-deterrent
system and have a new key made.
It is possible for the theft-deterrent
system decoder to learn the
transponder value of a new or
replacement key. Up to 10 keys
can be programmed for the vehicle.
The following procedure is for
programming additional keys only.
Canadian Owners: If the keys are
lost or damaged, only a dealer can
service the theft-deterrent system to
have new ones made. Two current
driver's keys are required to
program additional keys. To program a new key:
1. Verify that the new key has
PK3+ stamped on it.
2. Insert the current driver's key in the ignition and start the engine.
If the engine does not start see
your dealer for service.
3. After the engine has started, turn the key to LOCK/OFF, and
remove the key.
4. Insert the second current driver's key in the ignition and start the
engine within ten seconds of
removing the previous key. If the
engine does not start see your
dealer for service.
5. After the engine has started, turn the key to LOCK/OFF, and
remove the key. Insert the key
to be programmed and turn it to
ON/RUN within ten seconds of
removing the previous key.
The security light turns off once
the key has been programmed. 6. Repeat Steps 1 through 5 if
additional keys are to be
programmed.
If the security light comes on and
stays on while driving, the engine
will restart if you turn it off. However,
the theft-deterrent system is not
working properly and must be
serviced by your dealer. The
vehicle is not protected by the
theft-deterrent system at this time.
In an emergency, contact Roadside
Assistance. See Roadside
Assistance Program (U.S. and
Canada) on page 13‑7 orRoadside

Exterior Mirrors
Convex Mirrors
{WARNING
A convex mirror can make things,
like other vehicles, look farther
away than they really are. If you
cut too sharply into the right lane,
you could hit a vehicle on the
right. Check the inside mirror or
glance over your shoulder before
changing lanes.
The passenger side mirror is convex
shaped. A convex mirror's surface is
curved so more can be seen from
the driver seat.
Manual Mirrors
Adjust the mirrors by pressing the
mirror up and down and left and
right so you can see a clear view
behind you.

Seats and Restraints 3-13
{WARNING
You can be seriously injured,
or even killed, by not wearing
your safety belt properly.
.Never allow the lap or
shoulder belt to become
loose or twisted.
.Never wear the shoulder belt
under both arms or behind
your back.
.Never route the lap or
shoulder belt over an
armrest.
Lap-Shoulder Belt
All seating positions in the vehicle
have a lap-shoulder belt except for
the center front passenger position,
if equipped, which has a lap belt.
SeeLap Belt on page 3‑17 for more
information. The following instructions explain
how to wear a lap-shoulder belt
properly.
1. Adjust the seat, if the seat is
adjustable, so you can sit up
straight. To see how, see “Seats”
in the Index.
2. Pick up the latch plate and pull the belt across you. Do not let it
get twisted.
The lap-shoulder belt may lock if
you pull the belt across you very
quickly. If this happens, let the
belt go back slightly to unlock it.
Then pull the belt across you
more slowly.
If you ever pull the shoulder
portion of a passenger belt out
all the way, the child restraint
locking feature may be engaged.
If this happens, just let the belt
go back all the way and start
again.
Engaging the child restraint
locking feature in the right front
seating position may affect the passenger sensing system,
if equipped. See
Passenger
Sensing System on page 3‑26
for more information.
3. Push the latch plate into the buckle until it clicks.
Pull up on the latch plate to
make sure it is secure. If the belt
is not long enough, see Safety
Belt Extender on page 3‑18.
Position the release button on
the buckle so that the safety belt
could be quickly unbuckled if
necessary.

Black plate (18,1)Chevrolet Colorado Owner Manual - 2012
3-18 Seats and Restraints
To make the belt longer, tilt the latch
plate and pull it along the belt.
Buckle, position, and release it the
same way as the lap part of a
lap-shoulder belt.To make the belt shorter, pull its free
end as shown until the belt is snug.
If the belt is not long enough, see
Safety Belt Extender on page 3‑18.
Make sure the release button on the
buckle is positioned so you would
be able to unbuckle the safety belt
quickly if necessary.
Safety Belt Extender
If the vehicle's safety belt will fasten
around you, you should use it.
But if a safety belt is not long
enough, your dealer will order you
an extender. When you go in to
order it, take the heaviest coat you
will wear, so the extender will be
long enough for you. To help avoid
personal injury, do not let someone
else use it, and use it only for the
seat it is made to fit. The extender
has been designed for adults. Never
use it for securing child seats. To
wear it, attach it to the regular safety
belt. For more information, see the
instruction sheet that comes with
the extender.
Safety System Check
Now and then, check that the safety
belt reminder light, safety belts,
buckles, latch plates, retractors,
and anchorages are all working
properly. Look for any other loose or
damaged safety belt system parts
that might keep a safety belt system
